C. they both built pyramids. i hope you like it.
1. Inorganic combustion
2. Organic combustion
<h3>Further explanation</h3>
Given
The chemical equations
Required
Balanced equation
Solution
Organic compounds have the characteristic that there is a chain of carbon atoms, while inorganic does not have a chain of carbon atoms
The reaction of a substance with oxygen is called a combustion reaction
Complete combustion of carbon compounds will get CO₂ gas, whereas if it is not complete it will produce CO gas
So Organic : contain a carbon atom (and often a hydrogen atom)
1. Ca + O₂ ⇒ CaO₂
Inorganic combustion⇒does not contain carbon
2. C₃H₂O + 3O₂ → 3CO₂ + H₂O
Organic combustion
Local winds are mall scale convective winds of local
origin caused by temperature differences. Prevailing winds are winds that blow
predominantly from a single general
direction over a particular point on the Earth’s surface.
The volume of a substance is the quantity of the substance present at the definite temperature and pressure.
Explanation:
1ml of water has a volume of one cubic centimeter(1cm3). When a substance is cooled it causes the molecules to slow down and get close together occupies a smaller volume that results in density.
If the hot water is less dense it will float in room temperature and if the cold water is more dense it will sink in room temperature.
Density is the mass per unit volume of a substance. The density of water is given as 1g/cm3. It is mass divided by volume and water is used as the base for establishing the unit of mass which states cubic centimeter(1cm3) of water weighs one gram (1g). If the water is heated it expands or increases in volume. if the volume increases it becomes less dense.
A solid will start to melt when it reaches its melting point. For example the melting point of Helium is -272° Celsius and the melting point of Carbon is 3500° Celsius . Helium has the lowest melting point and carbon has the highest melting point in the periodic table.
